CONNEUTIOUT, A CORPORATION OF'NEW COVER-FEEDINGEMEANS.

Original application filed November 18, .1 923,.:Seria1' No..-7;5,-526. Divided and 'this application -fi1ed December .24, 4924.

This invention relates generally to blank feeding means and has more particularly reference to cover separating and feeding means for a seaming machine the character shown in application Ser. No. 675,526 filed November 18, 1923 of which application the present one is a .division.

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which:

Fig. 1 is a horizontal sectional view through a seaming machine and infeeding turret disclosing the generalarrangement of the parts.

Fig. 2 is a vertical sectional view on the plane of line 22 of Fig. 1.

Fig. 3 is a View in elevation of the infeeding turret and cover feeding devices associated therewith.

Fig. 4 is a top-plan fragmentary view, with parts broken away and in section, of the parts adjacent the infeeding turret and the cover feed mechanism.

Fig. 5 is a detail sectional view on the plane of line 5-5 of Fig. 4.

Fig. 6 is a perspective view of part-of the clutch mechanism for the cover feed mechanism,

Fig. 7 is a detail horizontal sectional view.

on the plane of line 77 of Fig. 5.

Fig. 8 is a vertical sectional View on the plane of irregular line 8-8 of Fig. 4.

Bodies are fed by conveyor chain 6 into the pockets of a rotating in-feeding turret 8, each pocket of which has a cover advancing member 9 which is in the form of a wing and which takes a cover from a cover source of supply 10 and feeds it into alinement with a can body to a work-holder in the heading mechanism generally designated by 11.

Any suitable means may be used to separate the covers from the stack 10 but, in the present instance, there are employed three spiral feeding-out rollers 72. These rollers are mounted on spindles 73 each of which carries at its upper end a pinion 74 meshing with a central idler 75. One of said pinions 74 drives idler 75 and the other two pinions 74 are driven from idler 75. The first mentioned pinion 74 meshes with an intermediate 76 and this intermediate meshes with a pinion 77 on shaft 78 that carries, at its upper end, another pinion 79 that receives its motion from gear 80 driven by gear 81 Serial: No. 757,819.

from shaft v54. Preferably, there is a clutch interposed; in this: train of gears whereby, no cover will be fed by the-spiral feeding-out rollers 72 unless a body has been fed; to receive a cover. The means used in this instance fer-effecting this nocan no cover control are asfollows: 82 is a detector member'mounted on rockshaft 83 and adaptedto project into the path of the bodies'advanccd by the turret over table 68. Connected with roekshaft 83 is an arm 84 from which extends a link 85 connected withnarms 86secured to rockshaft 87 supported on the framework andconnected with link .85 on upper arm 86 isconnecting rod 88, the other end of which-fis pivotally connected with arm 89 onrockshaft 90 which latter carries a bifurcated actuating member 91 that en gages a pin 92 carried by sliding member .93; and it will be understood that if a can body is present at the proper time against detector member 82, then through the connections-described-sliding member 93 is moved to the right thereby bringing it out of engagement with clutch-pin 94. Spring 873mm- 87 restoresparts to normal position. As will be seen, gear .77 is fast on shaft 78 but gear 79 is loose on said shaft and imparts its motion to said shaft by means of clutch member 95 which is fast to the shaft. Clutch member 95 carries clutch pin 94 which normally tends to descendinto ,open-ing 96 of member 97 secured to loose gear 79. Thetendency of clutch pin. 94 to descend intoopening 96-is due to expansion spring 98 and, so long as said clutch pin is in engagement with opening 96 power is transmitted from gear 79 to shaft 78 and thence to feeding-out rollers 72 of the cover feed mechanism. When, however, detector member 82 is not moved outwardly by a can body, then through the connections previously described, and by reason of spring 87 sliding member 93 will move to the left in Fig. 5 and cam face 99 will be in the plane of projection 100 of clutch pin 94 so that when rotation of clutch member 95 carrying said pin 94 brings the latter around to the point where sliding member 93 is located, then said clutch pin will ride up cam surface 99 and its lower end will thereby be withdrawn from opening 96 of gear 79 and hence no power will be transmitted to feeding-out, rollers 72. Referring to Fig. 8, it is preferred to interpose additional clutch mechanism in this train of gears which, however, is for a widely different purpose. It will be observed that gear 81 is loose on shaft 54 and is driven from said shaft by means of slipping clutch 101. In this way, rotation in one direction of shaft 54 will, through clutch 101, drive gear 81 and the cover feeding mechanism; but backward rotation of shaft 54, sometimes found useful in operating the machine by hand and setting it preliminarily for power operation, will fail to transmit power to gear 81 and hence the cover feed mechanism will not be operated.

The operation of the device is as follows: Can bodies are fed to the table 68 by the means described and are then engaged by one of the pockets in turret 8, the body passing by detector member 82, throwing the same outwardly, so as to render the transmission to the cover feeding-out roller 72 operative. The cover by rotation of member 72 is fed downwardly from a stack and eventually reaches channel member 71. As the body comes into position below the cover stack, wing 9 on the turret engages the lowermost and free cover resting in guide 71 and carries it along in alinement with the body until the point where guide 71 terminates at which point the body is placed on pedestal or lower chuck 49. When the cover reaches the end of guide 71, it drops on the body below and an upper chuck descends and the body and cover are clamped together.

I claim:

1. In a machine of the character set forth: a source of supply of covers, separating means for separating a cover from the source of supply, a train of gears for actuating said separating means including a clutching device consisting of a shaft, a gear driven from said shaft, a gear loosely mounted on said shaft, a clutch member mounted fast on said shaft, a clutch pin carried by the clutch member to engage the gear mounted loosely on the shaft, and a sliding member having a cam surface for raising the clutch pin out of engagement with the gear loose on the shaft.

2. In a machine of the character set forth: a source of supply of covers, separating means for separating a cover from the source of supply, a train of gears for actuating said separating means including a clutching device consisting of a shaft, a gear driven from said shaft, a gear loosely mounted on said shaft, a clutch member mounted fast on said shaft, a clutch pin carried by the clutch member to engage the gear mounted loosely on the shaft, a sliding member having a cam surface for raising the clutch pin out of engagement with the gear loose on the shaft, and a detector mechanism for moving said sliding member in one direction or the other dependent upon the absence or presence of a body.

3. In a machine of the character set forth: a source of supply of covers, separating means for separating a cover from the source of supply, a train of gears for actuating said separating means including a clutching device consisting of a shaft, a gear driven from said shaft, a gear loosely mounted on said shaft, a clutch member mounted fast on said shaft, a clutch pin carried by the clutch member to engage the gear mounted loosely on the shaft, a sliding member having a cam surface for raising the clutch pin out of engagement with the gear loose on the shaft a detector mechanism for moving said sliding member in one direction or the other dependent upon the absence or presence of a body, and means for feeding a cover that has been separated from the source of supply.
